geometry question on angles?

i have a homework question and if anyone could help, i would appreciate it. Thanks!

AB (line) and CD (line) intersect at E. If m <AEC= 5x-20 and m<BED= x+50, find in degrees, m<CEB

    5x-20 = x+50

    4x = 70, x = 17.5

    So these angles are 67.5

    BED = 180 - 67.5 = 112.5 degrees
